Women in early modern Scotland did not usually change their surnames on marriage, and she was known as "Jane Gordon, Lady Lochinvar", or "Lady Lochinvar". He was made
Viscount Kenmure in 1633 and he died on 12 September 1634. He had give in to Charles I's religious changes and he was remembered for that weakness, but she was always well regarded. She married again in 1640 to Sir Henry (Harry) Montgomerie and he died in 1644. She continued to use the title of "Viscountess Kenmore" and she was now the owner of her second husband's estates including the barony of Giffen, Ayrshire. In 1648 she accepted an offer from her father-in-law,
Alexander Montgomerie, 6th Earl of Eglinton. She gave him the barony in exchanges for a payment of 2,500 merks every year for life. In 1664, the book "Turtle Dove" by John Fullerton of Carleton was dedicated to her. Fullerton made his dedication by including an acrostic sonnet on "the name of the right honourable Lady JEAN CAMPBEL, Viscountess of Kenmoor". ==Biographies==
